3. INTRODUCTION
 Reactive power compensation and voltage regulation are two
effective measures to improve the voltage quality.
 By using new emerging technology the stability and reliability
of the system can be maintain very well using FACTS devices.
 Usually a STATCOM is installed to support electricity networks
that have a poor power factor and often poor voltage regulation.
 VAR compensation is defined as the management of reactive
power to improve the performance of ac power systems.

4. ELECTRICAL POWER
A. Active Power
B. Reactive Power
C. Apparent Power
In this we are compensating the Reactive power

5. REACTIVE POWER
What is Reactive power.
Need
Importance
Purpose
Sources

6. NEED FOR COMPENSATION
 The voltage regulation
 Increased system stability.
 Better utilization of the machines
connected to the system.
 Reducing losses associated with the
system.
 To prevent voltage collapse.

7. NEW VAR COMPENSATOR’S
TECHNOLOGY
 Static Synchronous Compensator (STATCOM),
 Static Synchronous Series Compensator (SSSC),
 Dynamic Voltage Restorer (DVR),
 Unified Power Flow Controller (UPFC),
 Interline Power Flow Controller (IPFC) and
 Superconducting Magnetic Energy Storage (SMES).

8. SINGLE LINE DIAGRAM OF
REACTIVE POWER COMP. USING STATCOM
Components mainly
used are :
 Coupling Transformer
 Voltage source
converter
 Capacitor bank
 STATCOM controller

9. VOLTAGE SOURCE CONVERTER (VSC)
In the figure, we have
represented ideal bidirectional switches. It
converts voltage and currents
from DC to AC while the
exchange of power can be in
both directions
• From AC to DC (rectifier
mode)
• From DC to AC (inverter
mode).

10. STATCOM CONTROLLER
 The strategy of STATCOM
controller is to keep the DC
capacitor voltage constant
while controlling the
modulation index to keep the
voltage constant during the
disturbance interval

11. PWM TECHNIQUE
 The amplitude of the
fundamental component
of the output voltage
VMOD, which can be
modified with the PWM
pattern as shown in
figure.
 When
VMOD › VCOMP
the VAR compensator
generates reactive power
and when
VMOD ‹ VCOMP
the compensator absorbs
reactive power
